Extending RED qdisc in ns-3 to support Cautious Adaptive RED (CARED) algorithm

Implementation of CARED algorithm in ns-3

Course Code: CS822

Assignment: #GP1

Overview

Cautious Adaptive RED (CARED) [1] is a two-in-one AQM algorithm that provides advantages of Adaptive RED (ARED) [2] and Refined Adaptive RED (RARED) [3]. The original paper of CARED used ns-2 [4] for comparing its performance against ARED and RARED. However, till date the implementation of CARED is not publicly available in any network simulator. This repository provides an implementation of CARED algorithm in ns-3 [5].

CARED example

An example program for CARED has been provided in

examples/traffic-control/adaptive-red-variants.cc

and should be executed as

./waf --run "adaptive-red-variants --queueDiscType=CARED"
